[FIX] web: template inheritance from dotted name

A good practice is to always prefix the name of a template by
the name of the module it is defined in.

So in the case where a template
```xml
<t t-name="module.template" />
```
was inherited by another

Before this commit, one should have written
```xml
<t t-name="other" t-inherit="module.module.template" />
```

After this commit, it becomes more natural, and one should only write
```xml
<t t-name="other" t-inherit="module.template"/>
```
